QPECIEECATION Aforming part of Letters Patent No. 338,428, dated :March 23, 1886,

Application filed June 17, 1885.

To all whom it may concern,.-

Be it known that I, ROBERT MITCHELL, of Atlanta, in the county of Fulton and State of Georgia, have invented a new and Improved Mosquito-Canopy, of which the following is afull, clear, and exact description.

My invention relates to mosquito-canopies, and more particularly to the tops of canopies for beds; and a special object ot' the invention is to facilitate the clearing of the insects from the space inclosed by the canopy, and by means of simple, durable, and efficient devices.

The invention comprises a mosquito-canopy top adapted to support the sides of the canopy fabric and connected to a hanger or arm support, and provided with opposite hinged lids or frames, the side arms ot' which engage each other, so that by drawing on one arm both lids will be opened for escape of the insects that are in the space inclosed by the canopy.

The invention consists, also, in particular constructions and combinations of parts ofthe canopy, all as hereinafter fullydescribed and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side view of my improved canopy,with the drooping sides ofthe netting indicated in dotted lines, and the top open. Fig. 2 is a central transverse sectional elevation of the same. Fig. 3 is aplan view of the canopy-top closed and partly broken away. Fig. 4 is an enlarged cross-sectional endwise view of the canopy-top in closed condition;

py-top as arranged upon a bar hinged and braced to a staff adapted for attachment to a bedstead, and showing the top open.

The letter Aindicates a frame of light metal or wood, shown square or rectangular in general forni, but which may be made round, oval, or of any other preferred form.

At B is shown the side mosquito-netting fabric,which is attached in any approved way to the frame A, so as to droop therefrom around a bedstead or other article of furniture or thing-to be inclosed for protection against insects.

Serial No. 169,966. (No model.)

The frame A may be suspended by its hanger C from a cord, C', fixed overhead, as in Figs. l and 2, or may be fixed to a bar, D, hinged at d to the head ofa post, E, adapted to be attached to the head-board of a bedstead, or the back of a chair or other article of furniture, braces at e e being provided, so that the canopy-top may be held up for use, and the braces are pivoted to the bar D and post E, and so attached to each other as to allow the entire head ortop frame,A, with its fabric B, to be folded down when out of use, or for inclosnre within afolding bed, to the headboard of which the post E may be attached.

The hanger O (shown only in Figs. 1 to 4,) consists preferably of a couple ofstrong wires, c c, twisted together for a distance both ways from the center of the hanger, where the suspension-cord O is attached, and near each end the wire strands c c are branched opposite ways and bent downward and inward to form pins c c', which are passed through holes in the frame A, to give a substantial support to the frame at each end of the frame.

The inwardly-projecting pinsc c are sufficiently long to form pivots to the opposite side frames,F G, which have eyes fg, respectively, fitted on the pivots on which the side frames may swing up from the top frame, A, upon which they fall normally by their own weight.

A suitable mosquito-netting fabric, H, is stretched across the canopy-top, and is secured to the frames F G, so that when these frames are closed the fabric H,with the fabric B, will form acomplete close canopy, asin Figs. 3 and 4, to exclude insects, and when the frames F G are swung open on their pivots o c', as in Figs. l, 2, and 5, anyinsects which may have found ltheir way inside the canopy may readily be driven from the open top of the canopy without requiring the persons occupying the bed to leave it and take the canopy down and turn it inside out to clear it of the insects, as must be done with canopies otherwise arranged.

To provide for opening the canopy top frames F G conveniently, I have extended one of the side arms of the` frame G, and bent it upon itself to form an elongated open loop or eye, I, and have extended the adjacent side IOO arm of the frame F, forming a rod, J, which is bent to pass through the loop I, and is eX- tended toward the center of the canopytop, and has a cord, K, attached to its end, which hangs down within reach of a person under the canopy.

It is evident that by pulling on the cord K that part of rod J which rests in the loop I will be swung down and will swing down the loop, so that the opposite frames, F G, will simultaneously be opened, the loop I being of proper length to limit the swing of the arm J, so that the frames F G will not swing up quite to a full opening, and hence will fall by gravity when the pull on the cord is relaxed. It only is necessary to draw on the cord to open the frames F G, and consequently the netting I-I at both sides of the top frame, A, and to hold the frames open for a sufficiently long time to drive the insects from the canopy, and at the same time secure better ventilation, and on slackening the cord the top will close automatically.

When the canopy-top is supported by the bar D and the post E, the bar will pass across the top of the frame A at its center, as indicated inJ dotted lines in Fig. 4.

lf preferred, the frame A may be made of heavy Wire, as are the frames F G shown, but any suitable materia-l may be employed in making the several parts of the canopy-top.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A mosquito canopy top comprising a frame, A, adapted to support the sides of the canopy fabric, opposite lids hinged to frame A to close it, a loop, I, on one lid, and a rod, J, on the other lid engaging loop I, substantially as described, whereby both lids Will be opened simultaneously by drawing on rod J, as herein set forth.

2. A mosquito canopy top comprising a frame, A, adapted to support the sides of the canopy fabric, and connected to a suitable support, opposite frames, F G, pivoted to frame A and covered by netting fabric H, a loop, I, on frame G, and a rod, J, on frame F, engaging loop I, substantially as herein set forth.

3. A mosquito canopy top comprising a frame, A, adapted to support the sides of the canopy fabric, and connected to a suitable snpport, opposite frames, F G, pivoted to frame A and covered by netting fabric H, a loop, I, on frame G, a rod, J, on frame F, engaging loop I, and a pull-cord, K, connected to rod J, substantially as herein set forth.

4E. The combination, in a mosquito-canopy, of the frame A, adapted to support the sides of the canopy fabric, a hanger, G, having branched arms c c, connecting with opposite ends of the frame A, and having inturned ends forming pivot-pins c c', opposite side frames, F G, pivoted on said pins and covered by netting H, a loop, I, on frame G, a rod, J, on frame F, engaging loop I, and a pull-cord, K, connected to rod J, substantially as herein set forth.
